SHOE-BEADING MACHINE.

To all whom it may concern v Be it known that I, EDWIN N. LIGHTFOOT, acitizen of the United States, residing at New York, in the county ofBronx and State of New York, have invented new and useful Improvementsin Shoe-Beading Machines, of which the following is a full, clear,concise, and exact description, reference being had to the accompanyingdrawing, forming a part of this specification.

This invention relates to shoe beading machines and more particularly toelectrical heating thereof.

These machines are employed in the manufacture of shoes for applying theornamental beading to the heel or other portion of the finished. shoe,the application of heat to the heading roll being essential to properfunctioning thereof.

Machines of this character have heretofore been heated by means of anopen gas flame applied at 01' near thefibeading roll.

This method, however, is dangerous, ineflicient and irregular in itsaction. The practically continuous pressure of inflammable or explosivegases in the air of shoe factories renders the use of an open flameexceedingly unsafe; While such flame is very easily extinguished ordeflected from its proper position by relatively slight air currents,and the soot produced by theflame is likely to soil and damage the work.It has also been proposed to heat such machines electrically but it isunderstood that no economical and convenient means have heretofore beenproposed for so heating the machines.

The present invention has among its objeets the provision of safe,economical and eflicient heating of machines of the character stated.

A further object is to incorporate an electrical heating element in amachine of the character stated in such relation as in no wise tointerfere with the use of such machine and to be readily attachablethereto and detachable therefrom.

Other objects and advantages will here inafter appear.

In the accompanying drawing, wherein is illustrated an embodiment of theinvention,

Figure 1 is a perspective View showing certain essential elements of thebeading machine together with the heating means therefor; and

Figs. 2 and 3 are enlarged detail views of the heating element.

Specification of Letters Patent.

Patented Nov. 6, 191 *7.

Application filed March 19, 1917. Serial No. 155,784.

Referring to the drawing, the beading machine illustratedcomprisesingeneral a pedestal 1, a beadingroll 2 mountedupon a rotatableshaft (not shown) which has'a suitable bearing 3 at the top of thepedestal, a casting 4 surrounding said shaft between the rollandpedestal and a work abutting plate 5 secured at the top of the pedestaladjacent the rolland casting. The beading roll 2 is securedv upon .theshaft by means of a screw retained plate 6, the shaft being power drivenby means of a belt '1 passing over a pulley 8 fast uponsaid shaft. Theroll 2,.however, is free for rotary slippage upon theshaft and whiletending to rotate therewith the same is subject to restraint throughengagement with the work. The casting l which provides a bearing for theusual work holding strap, is secured to the pedestal 1 bybeing clampedabouta reduced lateral extension of the bearing 3 by means of a clampingscrewv 9...

In the use ofithe machine, foriexample, in applying a bead to the heelof a shoe, the shoe is held with its heel base. firmly abutting theplate 5 andwithin the usualstra-p heel edge to be beaded is thus broughtin contact with themillededge of-the beading roll 2, the shoe beingprogressively rotated and shifted with. respect thereto to insure properapplication of t thebead without abrasion, it having been found inpractice that heating of the roll insures permanency of theindentations. and materially lessens the tendency to cut or scratch thework.

Referring to the heating means for the roll, the same includes a heatingelement 10 secured to the strap bearing casting 4 with which the saidroll is in intimate contact whereby the necessary heat is conducted tothe roll. For this purpose said casting is provided with a downwardlyand backwardly projecting portion 11 forming with the main body of thecasting an extended flat surface 12 to which the correspondingly shapedheating element 10 is intimately secured by means of screws 13. Thus theside edge of the heating element 10 extends for some distance in closeproximity to the rear face of the beading roll near its periphery,whereby heat is conveyed directly to the portion of the roll whichparticularly requires heating.

The heating element 10 comprises a pair of flat elongated heating units14, 15 welded or otherwise secured to the lower face of a fiatrectangular piece 16 of steel or other suitable material. The heatingun-its1 i,'15 are substantially of' the character disclosed and claimedin Patent N 0. 1,150,426,, granted August 17, 1915 to W. S. Had'away,.Tn, having at their contiguous ends. suitable screw terminals 17, 18the opposite ends of said units being electrieailybonnected to theregular operation of the machine.

What I claim as' new and desire to secure by Letters Patent is 1. Incombination, a pedestal, a beading roll revolubl'y supported thereby ina spaced relation thereto and an electrical heating element supportedbetween said pedestal and said roll and in close proximity to thelatter.

'2. In combination, a pedestal, a beading rollhaving a shaftrevofubl'ysupported by said pedestal and heating; means for saidrollincluding a heat conducting mass adjacent to said roll and saidshaftanda flat type electrical heating element disposed substantiallyperpendicularly and in close proximity to the rear face of said rel-1;.

3'. In a shoe machine, in combination, a pedestal, a heading rol-lrevolubly mounted thereon, a Work-bearing member fixed to. said pedestalin a projecting relation thereto and in close proximity to the innerface of said roll and an electrical heating element BEST AVAILABLE COP\1,245,745 i fixed to the under side of said member ad -j acent totheinner face of said roll."

4. In combination, a pedestal, a shaft revolubly mounted thereon andprojecting therefrom, a beading roll on said shaft, 2, Work-bearingmember surrounding said shaft and fixed in an offset relation to saidpedestal and in close proximity to said roll, said member having a fiatunder face and an electrical heating element of a fiat type fixed tosaid-face of said member in intimate contzicttherewith.

"5 ."Inashoe machine, in combination, a pedestal, a shaft 'revolubl-ymounted thereon and projecting therefrom, a heading roll on said shaft,a Work-bearing member surrounding said shaft and fixed in an offsetrelation to said-pedestaland in close proxto said roll, said memberhaving a downwardlyand rearWa-rdly-pro-jectingextension providing a flatunder face, and a fiat type electrical heating element fixed to saidface of"said member in intimate contact there- \V1th,"i3h6 edge ofsaidheating element extending'closeto the rear-face of said roll.

6. In a shoe machine, in: combination, a pedestal, a shaft projectingtherefrom, a beading roll on said shaft in spaced relation to saidpedestal and revoluble With respect thereto, a Work-bearing membersurrounding said shaft between said pedestal and said roli, said memberhaving a plane'under face substantially parallel to the axis of saidshaft and substantially perpendicular to the plane of said; roll and inclose proximity to the latter, and a fiat' type electrical heatingelement intimately secured to said face of said. member for heating thesame and the adjacent rolli In witness'whereof, I have hereuntosubscribed my name.
